KIRK S. BLANCHARD, OF BROOKLYN, NEW YORK.

` WATER-CLOSET.

Application led May 13, 1913.

To all whom it may concern: Y

Be it known that I, KIRK S. BLANCHARD, of Brooklyn, in the county ofKings, in the State of New York, have invented new and usefulImprovements in Water-Closets, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to certain improvements in water closetsinvolving the use of a motor-driven ventilator and flushing mechanismfor a purpose somewhat similar to that set forth in my Patents Nos.996,606, July 4, 1911, 1,025,364, May 7, 1912, and Patents Nos.1,114,575 and 1,114,576, both issued Oct. 20, 1914. j

Another object is to mount the ventilating fan and its water motorwithin the eX- tension of the bowl and preferably in a separate case orsupport so that the entire ventilating apparatus including the motor`may be easily and quickly removed or replacedat will. f

Other objects and uses relating to specific parts of the Ventilating`mechanism will be brought out in thefollowing description.

In the-drawings Figure l is a side elevation of the rear upper portionof my improved closet and seat therefor showing the extension forreceiving and supporting the various parts of the Ventilating andflushing mechanism. Fig. 2 is a top plan partly in section of the samemechanism exclusive of the seat. Fig. 3 is a transverse verticalsectional view through the extension taken on line 3 3, Fig. 2. Fig. 4is an enlarged longitudinal vertical sectional view through theextension taken on line H, Fig. 2.

In order that my invention may be clearly understood, I have shown acloset bowl --1- as provided with a rearwardly projecting chamberedextension -2- having a flushing chamber -3- and a ventilating chamber--4- separated from each other by a partition --5-, said chamberscommunicating with the interior of the bowl through separate passages-6- and -7-, the flush chamber 3- being connected directly to thepressure line or supply pipe -8- through the medium of a controllingvalve -9-- while the ventilating chamber -3- is provided with an outlet-10- adapted to be connected to a vent pipe (not shown) leading to theexterior of tie building in which the closet is locate Specicaton ofLetters Patent.

Patented Dec. 28, 1915.

serial No. 767,249.

The flush passage -G- preferably communicates with the bowl in a planebelow the `Ventilating passage -7-, which latter is located in the rearupper portion of the bowl just beneath the seat and is provided with aninwardly flaring mouth of considerable width but relatively shallowvertically so as to readily receive and convey the vitiated air from theinterior of the bowl when the fan is in operation or rather when thebowl is in use as will be hereinafter more fully explained. 1

The Ventilating chamber -4-- is provided ywith an opening in its outerside of suflicient size to receive a separate metal case 11-, theinterior of which is divided by a partition -12- into separatecoinpartments -13- and -14- for receiving a Ventilating fan -15- and awater motor -16 said motor and fan being mounted coaXially upon the sameshaft -17- which is journaled in a suitable bearing in the partition 12.

The fan compartment -18 is provided with a vent opening -18- in itsinner side communicating with the Ventilating chamber -4- as shown moreclearly in Figs. 2 and 3, and is also provided with a similar openingcommunicating with the vent pipe -10- as shown in Fig. 2.

The motor compartment 14- is provided with an outlet --19- registeringwith a similar outlet -20- leading directly into the interior of thebowl. The motor is driven by water under pressure directly from the mainline through a branch pipe 2lwhich is connected to a controlling valve-22- within and forming a part of the motor case -11-, the valve chamberbeing provided with a nozzle -23- discharging tangentially against theperipheral teeth or buckets of the motor as shown more clearly in Fig.4. The inlet pipe -21- enters a valve chamber -22- close to the end inwhich the discharge nozzle --23-w is secured so that the valve -22--which seats against the inner end of the discharge nozzle also coversthe adjacent portion to which the inlet pipe is connected, therebyconstituting a double closure.

The valve -22- is normally closed by a coil spring -24- which isinterposed between the upper end of the valve and a suitable adjustingplug or screw -25-- directly under and registered with a superposed butlarger screw plug 2G-- in the top of the bowl extension so as to permitaccess to the spring adjusting screw -25- and also to the valve whennecessary for adjustment or repairs. This valve is adapted to be openedlby downward pressure upon a seat, as for example when the latter isoccupied, for the purpose of operating the Ventilating fan during suchoccupancy` and to this end I have provided a valve-operating rod or rockshaft -27- which is journaled in suitable bearings in the upper rearpart of the bowl or extension so as to extend forwardly and rearwardlythereof with its front end directly under the rear portion of the seatand provided with a lateral offset 28- adapted to be engaged by saidseat when the latter is depressed for locking the shaft 27- whereby thevalve -22- will be raised from its seat, to admit the pressure fluid tothe motor through the discharge nozzle H23+ but, as soon as the pressureupon the closet seat is relieved and the seat returned to its normalposition, the valve -22- will be automatically closed by its spring -2lto permit the stoppage of the motor and ventilating fan.

The main supply and flush valve -9- is shown more clearly in Fig. 2 andcomprises a plunger valve -31- interposed between the inlet and outletof the valve case and normally seated at one end against a suitablevalve seat h32 facing the outlet of the valve case, and adapted to beopened by a hand-lever `fl3- having handle -44-- lVhat I claim is:

l. A water closet comprising a bowl having an integral rearwardextension provided with non-communicating chambers which communicatewith the interior of the bowl through separate outlet passages, meansfor supplying a flushing fluid to one vof said chambers, the otherchamber having a ventilating outlet, a ventilator case removably mountedin the last named chamber and having non-communicating compartments, awater motor in one of said compartments, a fan in the other compartmentdriven by said motor, and means for supplying a motive fluid to themotor chamber for driving the motor, the fan compartment havingcommunication with the chamber in which the ventilator case is locatedand also with the ventilating outlet.

Q. A water closet bowl having an integral rearward extension providedwith non-communicating chambers opening into the interior of the bowlthrough separate passages, a flush pipe leading to one of said chambers,a ventilator case removably mounted in the other chamber and providedwith non-com municating compartments, a water motor in one of saidcompartments, a fan in the other compartment `driven by said motor, andmeans for supplying a motive fluid to the water motor, said case havingan outlet connecting the motor compartment with the passage leading fromthe corresponding chamber of the bowl extension to the interior of thebowl7 the lfan `chamber having an inlet communicating with the interiorof such chamber and also provided with an outlet.

In witness whereof I have hereunto set my hand this 8th day of lllay,1913.
